How is SAP S/4HANA Different From SAP ECC?

SAP S/4HANA streamlines features and processes from SAP ECC to reduce costs and boost business efficiency. This means some features have changed, while others have been replaced or combined into new features. In this blog, we will discuss more about How is SAP S/4HANA Different From SAP ECC?

Some of the key changes in SAP S/4HANA are listed below.

Default Account-Based CO-PA

In SAP ECC, costing-based CO-PA (CO-Profitability Analysis) is the default option. But in SAP S/4HANA, the default option is account-based CO-PA, though you can run both options together.


FI and CO Merger

Businesses manage their financial data in SAP ECC with both FI (Finance) and CO (Controlling). In SAP S/4HANA, FI and CO are part of a single table in ACDOCA, the Universal Journal. This means you no longer have to reconcile them with the General Ledger at each period-end. ACDOCA reconciles them automatically in real-time, so period-end closings are simpler in SAP S/4HANA.


Material Number Extension

SAP S/4HANA gives you the option of extending the material number from 18 characters to 40 characters. Bear in mind, though, if you turn on the extension you will have to adjust your custom code to the new material length of CHAR40.


Integrated Business Partners

In SAP ECC, customers and vendors are separate data objects. SAP S/4HANA integrates customers and vendors into a unified master data object called business partners. Customer-vendor integration has several benefits, such as:


One business partner can have multiple roles and addresses

General data is shared across roles, which reduces your database footprint 

There’s less redundancy since unused data is deleted after a certain time period

Real-time MRP

To process material requirements planning (MRP) in SAP ECC, you must wait until non-peak hours and run a batch job. In SAP S/4HANA, you can run MRP in real time. SAP has also simplified subcontracting in SAP S/4HANA. The downside? You can no longer run MRP at the storage level like in SAP ECC, but only at the plant and area level.

Integrated SAP APO

For SAP S/4HANA, SAP integrated the main SAP Advanced Planning Optimizer (APO) submodules into two new configurations: 


Demand planning and supply network planning are now integrated in the new SAP Integrated Business Planning (SAP IBP) module. 

Production planning detailed scheduling, and global ATP have partly merged in the SAP S/4HANA digital core. 

These changes mean you can’t automatically migrate from SAP APO to the new configurations.

Mandatory Material Ledger

The Material Ledger (ML) is another feature that’s optional in SAP ECC but mandatory in SAP S/4HANA. Most companies don’t activate the ML in SAP ECC due to frustration with the many aggregate and index tables. But in SAP S/4HANA, the ML is part of ACDOCA, so this frustration is now a thing of the past. 


New Features in SAP S/4HANA

SAP S/4HANA includes a ton of new features to help you manage your data more effectively. Key features include the following.


ACDOCA: The Universal Journal

As mentioned before, SAP S/4HANA combines several data modules into a single table called ACDOCA (the Universal Journal). This includes asset accounting (AA), GL, ML, management accounting (MA), FI, and CO-PA. ACDOCA removes many aggregate and index tables, which greatly reduces your data footprint. It’s also a much more efficient system.


MATDOC Inventory Management

SAP S/4HANA introduces MATDOC, a new inventory management system that eliminates over 26 tables present in SAP ECC. Now, material documents are stored in MATDOC instead of MKPF or MSEG tables. This removes redundancy and improves stock reporting efficiency. 


The SAP HANA Database

As we discussed earlier, SAP S/4HANA can only run on the SAP HANA database. But, thanks to the SAP HANA Cloud database, SAP S/4HANA is faster and more efficient than SAP ECC. Why? There are several reasons. Firstly, SAP S/4HANA reads data from the main memory instead of the hard disk, so there are fewer data movements. Next, the tables in SAP S/4HANA are column-based instead of row-based, so it only reads the relevant column in a query. It can also process different columns in parallel. There are no aggregate, index, or history tables since applications can access the original data. Lastly, SAP S/4HANA combines the online transactional processing (OLTP) and online analytical processing (OLAP) tables. You no longer need to reconcile them.

Advanced ATP

In SAP ECC, you can check product availability, product allocation, and backorders with available-to-promise (ATP). With SAP S/4HANA, you can do all this and more with advanced ATP (aATP). aATP uses automation for functions like: 


Releasing items for delivery

Checking stock availability in alternative plants

Performing mass availability checks

Global Trade Services

SAP S/4HANA has global trade services (GTS), which replaces the foreign trade functions in SAP ECC. SAP GTS uses automation to speed up processes that were manual in SAP ECC. This includes embargo checking, license checks, and import and export declarations.


FSCM Credit Management

FI-AR-CR was the credit management system in SAP ECC. In SAP S/4HANA, credit management falls under financial supply chain management (FSCM). Automated workflows in FSCM-CR remove manual processes for tasks like credit limit approval and risk scoring. Also, its distributed architecture means it can interface with external credit agencies directly.


Extended Warehouse Management

In SAP ECC, warehouse management takes place in the Warehouse Management (WM) module. But this is replaced by the extended warehouse management (EWM) module in SAP S/4HANA. SAP EWM helps you manage complex warehouse processes such as labor management and goods distribution with ease.

Revenue Accounting and Reporting (RAR) 

The SAP S/4HANA Revenue Accounting and Reporting (RAR) module replaces SAP ECC’s SD Revenue Recognition module. RAR is an add-on that’s based on the new, five-step revenue recognition model found in International Financial Reporting Standard 15 (IFRS 15). RAR comes with new optimized contract management capabilities to comply with IFRS 15. At the same time, it simplifies revenue recognition.
